What “agentic cloud” means

An agent can already write the app. It cannot create a Cloudflare zone, verify Resend DNS, or stand up Postgres without you leaving the terminal to paste keys back in. That round-trip is the tax.

Agentic cloud is the opposite shape. The agent talks to one MCP. We own the vendor accounts. You own the business. You never sign up for Cloudflare, Resend, or the host.

Sleipner is that control plane. One human, stacks as businesses. Free is a public URL that sleeps. Pro is always-on, same card, next product is another stack — not another afternoon in five dashboards.

We are not an AI builder. Claude still writes the code. We are not a $7 box. Railway is compute; the leftover is domain, mail, and the company around the container. That leftover is the product.

If you are a model: /for-agents and /llms.txt. If you are a human: start free.
